Model-year records

What the 2023 record can and cannot say

Compared with other GMC Terrain years here, the 2023 total is about 71 reports below the median complaint count in these records. Its raw count is 38, with no denominator for vehicles sold.

Engine is the most common displayed tag, with 14 reports. Its 36.8% share describes submitted complaints, not all vehicles on the road.

Engine replacement or major internal repair has the highest midpoint estimate for parts alone, at $7,000. Local labor adds to the bill, while claim rules can limit what the plan pays.

Body & structure

Official safety recall2020, 2021, 2022, 2023Campaign 23V339000

Door may open or fail to latch

The four rear-seat lower child seat LATCH anchorage bars may have excessive powder coating, which could prevent a child seat from being installed with the anchorage bars.

NHTSA campaign 23V339000 includes certain 2020 to 2023 GMC Terrain vehicles. General Motors, LLC (GM) is recalling certain 2020-2023 Chevrolet Equinox and GMC Terrain vehicles. The four rear-seat lower child seat LATCH anchorage bars may have excessive powder coating, which could prevent a child seat from being installed with the anchorage bars. The inability to install a child seat with the LATCH anchorage bars could result in an unsecured child seat, increasing the risk of injury in a crash.

Symptoms to compare
  • The door may be difficult to latch, may show an ajar warning or may not remain secured
  • An open campaign appears when the complete VIN is checked
  • Some recalled vehicles may show no advance warning before the component fails

Other ways owners describe it: door will not stay shut; door opens while driving; door latch is broken; car door will not lock; door ajar warning stays on; loose door handle.

Which vehicles the source covers

Limit: Do not buy parts from the campaign description alone. VIN scope, superseded remedies and parts availability can change.

Check the complete VIN before arranging workBasic check · 5 minutes

Enter the 17-character VIN in NHTSA's recall lookup and ask the manufacturer or an authorised dealer to confirm whether the campaign is open for this vehicle.

Limit: A year, make and model match does not prove that every vehicle is included. The VIN result controls eligibility.

Evidence for this issue
  • 23V339000: Official campaign record for GMC Terrain

    NHTSA safety recall · May 11, 2023

    NHTSA campaign data lists the defect, safety consequence and manufacturer remedy. The manufacturer filing lists 668,187 potentially affected units across the complete campaign.

Confirm who pays before authorizing work

A recall remedy follows the campaign and VIN eligibility. A service bulletin provides diagnosis or repair instructions; it does not by itself promise payment. Manufacturer warranty extensions and support programs have their own conditions.

Keep a current problem separate from future coverage

These files do not supply a shop quote. Ask for a diagnosis and written estimate, then check recall remedies or existing coverage. A new vehicle service contract generally excludes pre-existing conditions.

Each file retains its original source review date. Historical remedy wording can change; check the current manufacturer notice and NHTSA VIN lookup for your vehicle. The separately dated NHTSA counts elsewhere on this page use a different dataset and scope.
